Emergency responders are those people who may be the first emergency personnel to arrive at hazardous material/waste incidents and are expected to take some evasive actions to protect the people or the environment. Most emergency responders are limited in their ability to perform aggressive actions due to lack of knowledge or training and lack of resources. Emergency response personnel must understand the Regularity Information & Rules and how to stay within the boundaries delimited by these Rules. These rules include OSHA, 29 CFR, Part 1910.120, Hazardous Waste Operation and Emergency Response and NFPA 472 Standard for Professional Competence of Responders to Hazardous Materials Incidents. A chemical spill incident is unlike other types of incidents in which emergency response personnel may be involved. Time is not as critical as at other incidents. Common sense must be applied at all times. Each incident response must be organized to develop a total plan of operation, including options to be exercised in the event of scene deterioration. Monitoring of clean-up contractors requires basic knowledge of procedures and regulatory aspects to ensure that safe and professional clean-up activities are conducted. Many responses by emergency service organizations have been conducted in a shooting from the hip mode. Emergency response personnel are learning by their mistakes, but those mistakes can be very costly.
